Application filed January 5,1907- Serial No. 350,880.

we, Lome-A. Knaus and Mor'r R.

rman, Illinois, and Moline, Illinois, respectively,

5 liaif', invented certain new and useful Improvements -in'FertilizeiDistributers, of which the following is a specification.

This invention relates to vfertilizer' distributers, and

iefers particularly to machines for spreading manure 10.

which comprise a rapidly revolving beater cylinder for discharging the manure and scattering it upon the ground. The object of this iriwllentionV is the production of means for cutting up long straws, plant stalks, or lumps of manure or other fertilizer, previous to its being'discharged from the machine by the beater cylinder.

In the accompanying drawings vFigure 1` is a side V elevation of the rear portion of a' manure spreader em.

bodying the features of our invention. Fig. 2=is a rear side elevation of that part of the manure-spreader l.mechanisms to which the present` invention relates.' F'g. 3 is a detail view of a pair of knives comprised in this embodiment of the invention. A

We have chosen to illustrate our present ments as applied to a manure spreader of the construe tion shown' in Patents Nos. 773,505 and 819,659, valthough it is to be understood that said improvements are equally susceptible of use in connectionpwith ,manure spreadersf of other constructions.` No limitation, therefore, isintended by the reference to our' patents above noted.Q

The box 1`oi the manure spreader herein illustrated comprises a movable bottom arranged to be moved rearwardlyto discharge the load, and to bel returned to normal positionby mechanism driven from the rear wheels 2. Attire rear end of the box 1 is rotatably supported the lbeater cylinder 3, the shaft 4 of which is provided at one end with a Vsprocket wheel 5. Upon the driving 'axle 6 is fixed a spur gear wheel 7 meshing with a.' pinion 8 mounted upon a shaft 9 .suitably supported beneath the boxl. j A sprocket wheel 10 is fixed with relation to the pinion 8, and carries a drive chain 11 lwhich also exteuds'over the sprocket whe .l 5. A tightener sheave: 12 "is rotatably supported upon an arm 13 pivotally mounted on one side of the box 1 in position to carry the upper side of the drive chain 11 at a point between the sprockets 5 and 10. By reason of the pivotal mounting of the arm 13, the tig' tener sheave 12 may be moved as required to take up slack in the chain l1, said arm being fixed in adjusted position, in this instance, by means of a screw bolt 14. extending through an elongated opening 15, said bolt being provided with a nut 16;

A rake 17 comprising teeth or tines 18 is pivotally improvel (not-illustrated in detail) bearing brackets 19 carriedby the box l. Anl arm 20 fixed with relation to said rake provides means'or swinging saidrake toward and away from the heater cylinder. The outer` end ofthe arm 20 is pivotally connected with the rear end ,of a connectingrod'21 mounted in proper relation to the beater cylinder 3 in 55 orming a part of the means for operating said rake.

In Fig. 1 the rake is shown in its rear or operative position.v l

A shaft 22 is rotatably supported at a point` above and rearwardly of the rake 17. Inthe present embodiment the means for thus supporting the shaft 22 com prises two brackets 23 each pivotally mounted upon a pivot pin or bolt 24 fixed in or upon the side of the box 1. A't a point between the endsof each bracket is formed an arcuate slot 25'and through said-slot extends suitable means for'rigidly securing the bracket.

in adjusted position, such as a bolt 26 (provi ed'- with a mit 27. The adjustable mounting of the brackets 23.

permits of adjusting the position of the shaft *22 and the parts carried thereb withrelation to' the b terv cylinder 3 and the rake 7. Upon the shaft 22 isip-y lported a series of cutting elements, such, for e m-I- le, as knives 28 arranged in any suitable way, as by, ygrouping them in pairs and spacing the pairs of knives as shown in Fig. 2.1 Throughout the 'greater portion of its length the shaft 22 is square in cross-section. The knives 28 ,have square openings 29 thereinto receive the shaft 22, said knives being secured in position upon said shaft in any suitable way, as,.`fo'r instance, by placing distance sleeves 30 een adjacent pairs of knives, and securing the series f knives and distance sleevestogether by means oi ycollars 31 fixed to the shaft 22. The knives -28 are provided with cutting` edges 32 and 33. v

The means yfor rotating the. series'of .cutting e'lements comprises a sprocket wheel 34 fixed upon one end of the cutter shaft 22 and a sprocket Wheel 35 rotatably mounted upon a stub-shaft 36 carried 'by one -of the brackets 23, a sprocket chain 37 extending over said sprocket wheels. A sprocket wheel y38 is fixed with relation to the sprocket wheel 35, and is engaged and rotated by the drive chain 11. Said drivechain.

is held in proper relation to the sprocket wheel 38 by means of the adjustable tightener sheave 12.

When the rake 17 is in operative position, the tines 100 18 thereof lie be een the pairs of knives'28, as illustrated in Figs. 1 a d 2. Said rake .prevents the discharge of large masses of material from the box 1 by the beater cylirilder 3. The knives 28 cut up all longl or matted fibers .or stalks, and assist the beater cylinder 3 in breaking up anylarge lumpsor masses of manure that may be present.
